Subject:  Final Update: Change in Satellite Broadcast Network
  (SBN) Effective from December 5, 2017, to
  January 16, 2018

Update issued to confirm termination of all SES-1 services

On January 16, 2018, the dual illumination of the Galaxy 28 (G-
28) and SES-1 satellite NOAAPort/SBN/NWWS services will
terminate with deactivation of the SES-1 NOAAPort/SBN/NWWS
interface. All current services will remain accessible via the
G-28 satellite.

NWS recommends all customers complete transitioning to the G-28
at their earliest opportunity to mitigate any unexpected issues
or problems which may be encountered prior to the SES-1
satellite NOAAPort/SBN/NWWS interface being deactivated.  At
this time, there are no planned extensions of the SES-1 services
by the NWS.
